ASTM B466 CuNi 70/30 Copper Nickel Elbow 45/90 Degree, Marine Grade Threaded Fitting
1. Product Description
Copper nickel elbow is a pipe elbow manufactured from copper-nickel alloy (CuNi), primarily used to change the flow direction of pipeline media. Common material grades include C70600 (90/10 copper nickel), C71500 (70/30 copper nickel), and BFe10-1-1. The product is formed by hot extrusion, cold pushing, or forging, followed by solution annealing treatment to ensure uniform microstructure and freedom from residual stress. With excellent seawater corrosion resistance, erosion resistance, and anti-marine fouling properties, copper nickel elbows are the preferred pipe fittings for marine engineering and corrosive fluid transportation systems. Various connection types are available: butt weld, socket weld, threaded, and flanged. Non-standard angles (e.g., 30°, 60°) and special dimensions can also be customized.
2.Product Applications
Copper nickel elbows are specifically designed for highly corrosive, high-velocity, and marine biofouling-prone environments. Typical applications include:
Shipbuilding: Cooling water lines, ballast systems, firefighting systems, seawater mains, and tank cleaning systems on commercial vessels and naval ships.
Offshore Oil & Gas Platforms: Seawater lift risers, heat exchanger piping, water injection systems, and process lines.
Desalination Plants: Seawater transmission pipelines in reverse osmosis (RO) and multi-stage flash (MSF) processes, resistant to high-velocity erosion.
Power Industry: Auxiliary cooling water systems, condenser piping, and industrial water networks in nuclear and thermal power plants.
Petrochemical Industry: Handling corrosive media containing chlorides or sulfides, such as heat exchangers, condensers, and certain process lines.
HVAC & Refrigeration: Central air conditioning cooling water systems, chilled water systems, and industrial cooling circuits.
3.Product Functions
Change fluid direction: Achieve smooth direction changes of 45°, 90°, 180°, and custom angles in pipeline systems, reducing local vortices and energy loss.
Connect pipe sections: Serve as corner joints, working with straight pipes, flanges, tees, reducers, caps, etc., to form a complete transportation network.
Pressure & temperature containment: Safely and sealably convey media within specified pressure ratings (up to CL6000 / PN40) and temperature ranges (-196℃ ~ +350℃).
Corrosion barrier: Protect the piping system from rapid attack in corrosive environments, especially preventing leak accidents caused by localized corrosion.
Simplify system design: Due to the material‘s excellent comprehensive performance, reduce the need for additional measures such as corrosion-resistant linings, cathodic protection, or inhibitors, simplifying system design and maintenance procedures.
